The operation fails.
Ensure that the DEVICE parameter that is associated with the library is identified correctly in the DEFINE PATH command and that the library device is turned on and ready. If the library has an access door, make sure it is closed. If a cleaning threshold is exceeded for a tape drive in this library, clean the tape drive. For more information about the values of the KEY, ASC, and ASCQ fields, see the library and drive reference manuals.
